Sadly, it seems the current behavior is hard-coded (see the
'completionHandle' function here:

  http://xmonad.org/xmonad-docs/xmonad-contrib/src/XMonad-Prompt.html

) There doesn't seem to be a way to configure things to get the
behavior you want.  It does seem like a sensible behavior though, and
of course patches to XMonad.Prompt allowing it to be configured would
be welcome.
